Web15 nov. 2024 · ASCII coding uses 8 bits (1 byte) to represent one letter. But using Huffman coding this is being reduced to 119bits. The compressed message is 45.08% of the original message. Web25 okt. 2024 · Therefore, a total of 120 bits ( 8 bits x 15 characters ) is required to send this string over a network. We can reduce the size of the string to a smaller extent using Huffman Coding Algorithm. In this algorithm first we create a tree using the frequencies of characters and then assign a code to each character.

Web23 aug. 1997 · Here, instead of each code being a series of numbers between 0 and 9, each code is a series of bits, either 0 or 1. Instead of each code representing a phone, each code represents an element in a specific ``alphabet'' (such as the set of ASCII characters, which is the primary but not the only use of Huffman coding in DEFLATE). Huffman tree generated from the exact frequencies of the text "this is an example of a huffman tree". The frequencies and codes of each character are below. Encoding the sentence with this code requires 135 (or 147) bits, as opposed to 288 (or 180) bits if 36 characters of 8 (or 5) bits were used.
